Wera Tools Joker

17+19 x 235mm, Stainless steel Double open-ended wrench; holding function with the metal plate in the jaw reduces the danger of losing bolts and nuts; exchangeable metal plate in the jaw with extra hard teeth secures bolts and nuts and reduces the risk of slipping; the integrated limit stop can prevent any slipping downwards from the screw head and allows a higher torque to be applied; the double-hex geometry creates a form-fitting connection with the nut or bolt and thereby lowers the risk of any slipping; a return angle of only 30° to avoid the need for any time-consuming turning of the wrench in screwdriving applications; special forged geometry for high torque transfer and great rigidity against bending; high performance chrome-molybdenum steel; nickel-chrome coating for enhanced corrosion resistance.
